“In any camera that allows you to have control over aperture, the aperture setting is done using what is referred to as F stops. For example, in my Canon G5, the F stops are as follows. 2.0, 2.2, 2.5, 2.8, 3.2, 3.5, 4.0, 4.5, 5.0, 5.6, 6.3, 7.1, 8.0. What this means is, I can set the Aperture on my Canon G5 to any of these values. So what does it mean to set the aperture to F2.0 or F4.5 etc ? Every newbie, faces some confusions with these F numbers.”
